Updating data in a mobile terminal

摘要

A method of differentially updating stored data in a mobile terminal from a first data version to an updated data version. The method comprises detecting whether the stored data in the mobile terminal includes one or more corrupted portions of the stored data inconsistent with the first data version; loading differential update instructions into the mobile terminal; and generating the updated data version by the mobile terminal from the stored data and the loaded differential update instructions, including repairing any detected corrupted portions.
